从关系中检索相关记录

Question

我允许用户按类型搜索传递给函数：

public function typeSearch($type)
{
    $events = Event::where('type', $type)
        ->with('entities')
        ->get();
    return view('events.searchResultEvents', compact('events'));
}

它的作用几乎与它应该做的一样，它确实检索实体但不是正确的实体，例如：

事件id = 25，entity_id = 2它检索：实体id = 25，而它应该是2.

如何更改此权限以便检索正确的记录？

实施例::

查看图像，Event is = 25且entity_id = 1.entity_id是一个外键，它链接到＆＃39;实体上的id。表

来自关系我们拥有＆＃39;实体＆＃39; id = 25，而它应该是1，因为entity_id = 1

活动模型::

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Laravel\Scout\Searchable;

class Event extends Model
{
    protected $table = 'events';
    public $timestamps = true;

    use Searchable;

    public function entities()
    {
        return $this->belongsTo('App\Entity', 'id');
    }
    public function users()
    {
        return $this->belongsTo('App\User', 'id');
    }
    public function events()
    {
        return $this->belongsTo('App\DirtyEvent', 'id');
    }
}

Answer 1

我认为您的关系方法存在问题。

public function entities()
{
    return $this->belongsTo('App\Entity', 'id'); // Ithink you need to change it
}

将第二个参数中的'id'更改为'entity_id'

public function entities()
{
    return $this->belongsTo('App\Entity', 'entity_id');
}

第二个参数是这样使用的，我不知道如何在技术上解释它，但这是一个例子：

$event = Event::find(1); 
//this will return the events with id=1 and that data have entity_id=2

$entities = $event->entities;
//If you set the second parameter in your Event model to 'id', 
//this $entities variable contain the data from entities table with id=1, because your $event id=1

//But if you set the second parameter to 'entity_id'
//this $entities variable contain the data from entities with the id=2, because your $event entity_id=2
